I'm in a crowded waiting room and a man just loudly informed us all he is "cybersecurity expert" so I automatically assumed that meant he's an IT guy* who installs antivirus software. The actual cyber security people in this town won't tell you what they do or even where they work sometimes let alone claim to be experts.
*No offense to IT people, your job has value and you have expertise!
@Gogogadgetpants I usually assume anyone who refers to themselves as an expert is an expert at bragging and little else
@Gogogadgetpants Maybe it's double-backflip cybersecurity social engineering misdirection.
So you obviously can't drink from the glass in front of you...
